This invention relates to a novel and improved type of absorbent; sea g cap, to be applied to bottles and similar containers and substantially has for its object a novel type of such device provided on its outer surface with means adapted to absorb the uid material contained in the container and be kept in a suitable condition of impregnation or imbibltion, so as to allow of said absorbent and impregnated means to be used by rubbing against or on any desired surface, for the treatment of the same with said :duid material.

Owing to its convenient features of construction and arrangement, the improved type of sealing cap which forms the object of this invention, may conveniently be used for cleaning clothes and the like, although it may as well be used for treating other surfaces for any desired purposes.

The invention also views other objects which will appear and be understood from the following description of the device.

In order that the invention may be readily understood and carried into practice without difficulty, a preferred embodiment of the same has been shown by way of example in the accompanying illustrative drawing which shows a partial longitudinal section of a container for fluid material, provided with the novel type of sealing cap in accordance with this invention.

In the form of construction shown, the reference number I indicates a bottle or similar container for fluids, of the usual type, the neck 2 of which is formed on its outer surface with screw threads 3, for screwing thereon a corresponding screw cap. The lower part of the neck is formed with a plain section 4 which provides a seat for a Washer 5 of cork or other suitable material, for securing a tight closure of said cap.

According to this invention, the sealing cap substantially consists of a nozzle member 6, provided on its inner surface with screw threads 1, adapted to engage with the threaded part 3 of the neck 2, the outer surface of the cover being slightly tapering or conical in shape and ending at its base part, of largest diameter with a peripheral flange or shoulder 9, adapted to bear with its lower edge on the aforementioned Washer 5, thus forming a perfectly tight closure.

By reference to the drawing it will also be seen that in the upper surface of said nozzle member 6, a recess l0 of suitable depth is formed, adapted to house a disc II, of felt or other suitable absorbent material, of which the outer surrace I2, slightly spherical in shape, is covered by an applicator fabric in the form of a changeable piece of cloth or similar material I3, held in position by a suitable ring or hoop I4 which may be applied with an adjustable degree of pressure around the external surface 8 of said cover 6.

To the lower end of the nozzle member E, a thin disc I5 is applied, so as to act as a packing between the base of said nozzle member and the rim of the neck 2, thereby forming a tight seal between both parts.

If necessary, an annular groove I6 and a central recess Il may be formed on the upper and lower faces, respectively, of the nozzle member 6, the former of the same being lled with the same material which forms the disc II.

It will further be seen, by referring to the drawing, that at the central part of the end wall of the nozzle member 6, another small recess I8 is formed, directed toward the lower end of the same and extending in a downward direction so as to form a small frangible appendix or extension I 9, partially provided with a narrow longitudinal duct 20 and formed on its outer surface with a peripheral groove 2| which serves as a seat for the rim of a narrow opening formed at the centre of the disc I5. Within the recess I8,l a small spherical valve 22 is housed, adapted to obturate the outlet of the duct 20.

The whole device, as above described, is covered at its upper end with a second cover 23, screwed onto the screw threads 24 provided on the outer surface of the peripheric rim 9, while its lower edge is adapted to tightly bear on the washer 5, mentioned before.

The extension I9 which obturates the outlet of the duct 20 has forits object to prevent any leakage of the fluid contained in the container I, owing to evaporation or to any other cause, while serving at the same time to warrent the purchaser as to the genuineness of said contents, since said extension only is to be detached when initiating the use of the same, for which purpose it will be suiicient to disengage the nozzle member 6 .and cover 23 and then break or tear said extension along the groove 2|, after which the parts E and 23 may be replaced in position.

For using the device above described, the outer cover 23 is removed, the position of the container i is reversed, so as to cause the valve 23 to open under the action of its own weight, thereby allowing of the discharge of a suitable amount of the fluid contained in the container by the duct 20, until the pad of felt or the like, formed by the disc I I and the outer lining I 2 has become sutiiciently impregnated or imbided; after this,

the said pad may be rubbed against the cloth or other surface to be treated for cleaning the same or for other purposes. After this, the container is reverted to its normal position, whereby the seal of the valve 22 will close and the outer cover or cap 23 is finally replaced in position.

When the device is being used as a means for cleaning stains,...itwil1 be necessaryv to replace. from time yto itime4 the cover or lining I3, for which purpose the hoop or ring I4 is removed and after a fresh lining having been placed in position, the hoop i4 is again forced home, against the conical surface 8.

From the foregoing description, the invention will have clearly been understood and no'further'..

explanation will .be required by those skilled 'in the art.
